Using Avaya Site Administration to set up a TOD synchronization schedule
Determining location offset values
The Avaya Site Administration Time Synchronization feature sends synchronization
messages to a switch that are specified in Standard Time using the set time command.
To calculate offset values that represent the time difference between the Avaya Site
Administration client PC and switch locations, all location times should be normalized to
their Standard Time equivalents.

Important: Important:
Always calculate offset values based on comparisons between Standard
Important:
Time equivalents. Otherwise, if Daylight Savings Time rules are not the
same for the Avaya Site Administration PC client location and a target
switch location, significant synchronization errors can result.
The following table uses the switch locations described in the example scenario to derive
correct offset values for the client PC and switch locations.
Note:
The local times listed in the table are arbitrary in nature, and are intended
Note:
only to illustrate the time differences between locations. You can use any set
of relative location times for this purpose.
